IMPROVEMENT IN BASE-BURNING- STOVES.

I The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that I, JOSEPH O. Hnxnnnsox, of the city of Troy, in the county of Rensselaer, and State of New York, have invented a new and useful Improvementin Magazine-Stove s; and I further deolare that the following is a full, clear, and exact description of my said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which 7 Figures 1 and 2 are perpendicular sections of my improved stove;

Figure 3 is a horizontal section, showing the manner in which the air is introduced to the annular chamber or ring at the bottom of the magazine;

Figure 4 is also a horizontal section, showing the mode of introducing the air in the space between the double'walls of the magazine;

Figure 5 is a representation of the interior of the oven placed at the top of the stove; and

Figure 6 is a perspective View of the exterior of said stove.

My invention relates to that species of magazine stoves havingv the supply-cylinder or magazine suspended over the fire-pot, and'not continuous; and

It consists in constructing. the supply-cylinder in such a manner as to supply air from the exterior to the surface of the fire, to promote combustion, and also to supply heated air to an oven placed at the top of the stove, or to the room, as may be desired.

It also consists in forming the top of the stove into an oven, wholly disconnected from the combustionchamber or fines of said stove, and to which heated air from said supply-cylinder is admitted, substantially as described.

It also consists in the employment of a damper in the ,cover of said oven, by means of which the heated air can be confined to the oven, for the purpose of baking, or allowed to escape into and warm the at'mos:

phere of the room.

' these results in the same stove, heated air being supplied to the fire, and also to the room, or, if desired, to the oven at the top of the stove.

A is the combustion-chamber, l3, the fire-pot, and O, the magazine or supply-cylinder of a common selffeeding stove.

I construct the cylinder 0 with double walls, so that between saidwalls there is a space, constituting the air-chamber a a.

' At the top of this air-chamber are apertures b 1), opening into the oven D.

The air is supplied to this chamber a a by means of the air-flue or passage E, connecting with the exterior atmosphere. I

At the bottom of the suspended cylinder 0, I construct. an annular tube or chamber, F, surrounding the bottom of said cylinder, and firmly attached thereto, and communicating with the air on the outside of the stove by means of the said flue or passage G.

This annular tube or air-chamber is perforated at the bottom with small holes e e, through whichfthe air passes directly to the surface of the tire.

Between the top of the supply-cylinder G and the exterior of the stove, I place a circular plate, dd, thus This oven is closed by'the cover H forming the top of the stove.

In said cover H are the small apertures g g, close by the damper I, when desirable. The operation of my said invention is as follows:

After the fire is kindled, and the annular tube or chamber F becomes heated, the exterior air will pass, through the fine G, to said chamber, and, passing, through the small apertures efc, to the surface of the fire, will greatly aid in promoting the complete combustion of the fuel and of the gases evolved therefrom.

As the cylinder G becomes heated, the air will enter the-air-ohamber a a, formed by the double walls of said cylinder, and, after being thoroughly heated,- will escape, through the apertures I) b, into the oven I).

\Vhen it is desired to use said oven for baking, the apertures g g, in the cover H,are closed by the damper 1, and the heated air from the chamber a a will be retained in the oven. As it becomes cooled, it will be displaced by the more highly-heated air from the said chamber a a. Thus a current of hot air through said oven will be established, thoroughly ventilating the oven, and causing it to bake with facility.

\Vhen the oven is not in use, the damperI is opened,

and the hot air, passing through the apertures g y, is diffused throughout the room, thus adding greatly to the heating-properties 0f the stove.

What I claim as new, and desire to secure by Letters Patent, is-

1. The supply-cylinder or magazine 0, constructed with double walls, enclosing the air-chamber a a,with cover H, a-pertures g g,and damper I, all armnged the apertures b b, the perforated annular tube or air- 7 and combined substantially as hereinbefore' specified chamber F, and the aireflues E and G, all arranged and set forth.

and combined substantially as hereinbefore specified. In witness whereof, I have hereunto set my hand, 7 2. The oven 1), in combination with the cylinder this 8th day of March, 1869.

O, air-chamber a a, andeir-flue 0r passage E, sub- J. G; HENDERSON. stantially as and for the purposes hereinbefore de- Witnesses:
